The Fuelpak can be plugged in without removing the old program but the settings for your combo that V&H gives you won't work right since the base settings aren't stock.
It looks like you're going to need some help, either to install a good map like LL posted or to return the ECM to factory settings.
So, what you guys think I shoud do? Have the dealer remap it all using the SE Efi race tuner and put the new fuelpak I just bought up on eBay or list it here and count my losses??
Or shoud I reset the PCM to stock and use the fuelpak?
I'm a noobie with the V-Rod modding. I bought it new in 07 started modding it in 08 and have had it sit for the last 2 years..
Now, I'm itching again. Luckily in time for the snow...
i would use the race tuner , ask the dealer if he can show you how to install the map , you will need to just get one off here (ll posted a link) put it on a stick or save it on your computor then take both computer and stick into the dealer with your bike and ask them to show you , you might have to pay them probably an hour labor but then youll know how .
Or you could post on this site and I am sure someone will walk you through it . It was not hard to do , im sure you can
